RAILWAY LAMP.

Application led March 29, 1926. Serial No. 98,167.

The invention is a lamp that is particularly adaptable for brakemc-n orrailroad employees, and which may be removably attached to a band onapersons wrist and supplied by current :trom a battery in a pocket on a.belt.

The object of the invention is toprovide a light that does not have t0be carried, and which is at the same time readily removable from thebody.

A further object of the invention is'to provide a light that may bereadily attached to any part of the body, and readily lighted from acommon point.

provide a lamp that may be attached to the body, and readily adjusted toany suitable position.

And a still further object of the invention is to Yprovide a readilydetachable body lamp which is of a simple and economical construction.

Vith these ends in view the invention embodies a tubular lamp casinghaving a at the inner end, a socket into which the said tubular casingmay be sprung and held, means for attaching the socket to any suitablepart of the body, a battery, a. switch on the battery, a belt in whichthe battery may be placed, and means for connecting the said battery tothe said lamp socket.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawings, wherein: y

Figure 1 is a view showing the device as it would appear in use.

Figure 2 is a plan view showing the lamp casing and socket.

Figure 3 is a similar view showing an alternate design, in which twolamp sockets are used instead of one.

Figure 4 is a longitudinal section through the lamp casing and socketfor holding the said casing. Y

Figure 5 is a cross sectionl through the socket showing a spring forholding the lamp casing therein.

In the drawings the device is shown as it would be made wherein numeral1 indicates the lamp casing` numeral 2 the socket and numeral 3 thebattery.

The casing 1 is made as shown with a socket 4 at the outer end, having areflector 5 held therein, and a tongue 6 at the inner end lamp.

A further object of the invention is to lamp socket in the outer end,and a tongue with a notch 7 in the lower side, and a contact point 8 atthe end. It will be noted that the contact point 8 is insulated from thecasing and connected to another vcontact point 9 at the opposite end ofth-e casing, through a wire or rod 10. It will be noted that the lampbase will contact .with the casing through the socket 4 and the contactpointvatA the bottom of the lamp base will engage the contact point 9 atthe base of the The contact point S will engage another point 11 in thecnd of the casing and the exterior' of the casing will 'form a contactwith they casing 2.

The casing 2 is providedl with a boss 12 to which a double wire cord 18is attached, and one wire of the cord is grounded to the casingl asshown at the point 14, and the other wire is connected to the contactpoint 11. The casing 2 is provided with a socket 15 having a spring 1Gin the lower side, and it will be observed that as the 'tongue 6 isplaced into the socket 15 the notch 7 will pass over the spring 16 sothat the spring will snap into the notch to positively hold the tongueof the casing 1 in the socket. The tongue may readily be released bypressing the outer end of the spring 16 downward. In the design shownthe casing@ is provided withloops 17 by which it may be attached to awrist band or the like.

The battery 3 maybe of any suitable type or size, and may be held in apocket 18 in a belt 19, as shown in Figure 1. Thepocket 18 may be of anysuitable shape or design, and the contacts with the battery may bearranged in any suitable manner. The pocket is provided with a switch 2Owhich may be arranged to light the lamp on either hand or on the cap,orto extinguish all the lamps. However, it is understood that shouldonly-one of the lamps be sed the switch may be adaptable to light onlyone lamp, or any combination of lamps. it will be observed that thecords 13 will extend from the pocket 1S to the individual lamp socketsthrough the clothing. These cords may be of any suitable length andarranged in any suitable manner to permit the lamps to be changed fromone position to another, as may be desired.

It will be understood that changes may be v` made in the constructionwithout departing from the spirit of the invention. One of which changesmay be in the design of the lamp casing, another may be in the design orYstood from the foregoing description.

arrangement of the socket or in the means of attaching the lamp casingto it, and still another may be in the design, arrangement or positionof the battery. I Y

The construction Will be readily under- To use the device it may bearranged as shown, and it will be observed that when it is not in usethe lamp casing may readily be removed from the socket 2 and placed in apocket, and only placed in the socket when it is desired to use it. Thelamp may then be lighted by the switch 20, as may be desired.

Having thus fully described the invention, what I claim as new anddesire tosecure by Letters latent, is: A

l. In a railway lamp, a. detachablelamp casing, a socket in which thelamp casing may'readily be held, a spring latch in the.

said socket for readily holding the end of the said lamp casing,suitable contactpoints in the said socketadaptable to engagecorresponding contact points on the end of the said lamp casing,suitable Wires extending from the contact points at the end of the saidlamp casing through the said 'casing and connecting to the lamp socketto light the lamp, and a suitable two Wire cable eX- tending from thecontact points 1n the said socket, means for attaching the socket to a'lighting the said lamp vas desired.

2. In a lamp, a tubular casing, a lamp socket in the outer end of thecasing, ay tongue at the inner end of the casing, Contact points on thesaid tongue, suitable electric connections from the contact points onthe tongue to the lamp socket through the tubular casing, a socket intowhich the said tongue may be placed7 contact points in the said socketcorresponding with the Contact points of the tongue, means for holdingthe tongue in the said socket, means for attaching the socket to a partof a persons body, a battery, means for attaching the battery to a partof a personls body, and means for connecting the said contact of thesocket to the said battery.

Y In testimony whereof he aiiixes his signature.
